This was an energy return on energy investment (EROI) of 100:1. It is, convinced that Planet Earth is under such severe resource and environmental stress, even now being incapable of feeding, clothing, housing, etc. And when it comes to early childhood programs, some less wealthy countries spend as much as 2% of GDP, compared to Canada’s 0.3%. Contact the CMPA for context-specific medical-legal advice regarding the delivery of care to patients in these challenging circumstances. On the other hand, my wife is involved in a group called Save Our Fine Arts. The Yangtze and Ganges rivers are heavily polluted, and the Nile is a trickle by the time it reaches the Mediterranean Sea, its waters having been drawn upon by growing populations in Ethiopia, Sudan, and Egypt. The vast Canadian Shield, with its masses of igneous and metamorphic rocks, contains numerous large deposits. However, if now there are looming resource shortages it is every bit as much due to Man’s exponential increase in numbers as to his profligacy. But oil is a non-renewable mineral as well and is available in many different forms in reserves requiring many different levels of effort to exploit. Here, access to family planning is critically important. Current world oil production is averaging EROIs in the region of 15 to 20:1. They could not buy this type of support with either money or time alone. Metallic ore grades are falling globally as the higher grade reserves are exploited first and are progressively depleted. So net EROI is 4:1 In 1950, only 1% of energy from oil was used to discover and produce more oil. Code for cheap, dense, flexible energy. Very few show a declining Human Effort Index. Less than a handful of people showed up, and it ended up being a lot of work. I won’t weigh in on this debate, but it’s interesting to look at the total cost of health care as “time+money”. Metallic minerals are also found in such rock types in the Western Cordillera and the Appalachians. The Arrival of Peak Lead: Peak Environmental Impacts, The peak of world oil production, followed by an irreversible decline, will be a watershed in human history. Like the more general society-wide condition of scarcity, a given resource is scarce because it has a limited availability in combination with a greater (potentially unlimited) productive use. Access from your area has been temporarily limited for security reasons. Scarce resources are used to produce scarce goods. Before the pandemic, ever-increasing globalization meant many workers were employed in precarious, low-wage work with few, if any, benefits. Networking is key, but not really a scarce resource. For a reserve with and EROI of 5:1, the net output per barrel input is 4 barrels. How have you developed relationships? This trend is compounded by the increase in cost of energy which is the one resource necessary to exploit, process and distribute every other resource. Immediately upon becoming Prime Minister in 2006, Stephen Harper cancelled agreements with all provinces and territories that were intended to form the basis for Canada’s first national child care program — together with the federal dollars that went with them. Human societies face a threatening future of resource scarcity and environmental damages. Physician care is judged not on a standard of perfection, but rather on the standard of care that might reasonably be applied by a colleague in similar circumstances. The opinions expressed are my own. I got all my jobs through networking. The scarcity of resources may continue once COVID-19 subsides. It is important to recognise the links between gold production trends and resource intensity, as this is critical for understanding future sustainability challenges. In the event. Visit the. Public health care provides care first to those who can spend their time in line. However, oil has ceased to be almost free. This is illustrated in the dictum that “it’s not what you know, but who you know.”. As output from the much lower EROI oil sands comes to dominate, the overall EROI is dropping continuously. An excellent example of the tension between the scarce resources, in my mind, is the debate around public vs. private health care. Is it the success that attracted the large network, or the large network that supported their success. Humans have always exploited the most accessible and richest resources first. The EROI of wind energy is in the neighbourhood of 12 to 14:1. For a reserve with an EROI of 100:1, the net amount of oil produced by 1 barrel of input is 99 barrels output. Canada’s unions join communities across the country to mourn and to call for action. The economic view doesn’t entirely conform to reality, but it provides a useful working model. Fortunately, copper is relatively abundant. It’s now more than 40 years since the Royal Commission on the Status of Women first called for a national child care program. Without federal financing and leadership and with widely divergent provincial/territorial programs, high quality affordable child care is a scarce resource in most of Canada. There is no perfect solution to address resource dilemmas. I think one feeds the other. In Canada in the late 1800s, the average yield of copper per tonne of rock was 90 pounds or 4.5%). _uacct = "UA-1512599-2";
It is estimated that 37 per cent of Canada’s total freshwater is contained in the three territories. Ethiopia also, like all Sahel countries, is now largely deforested, not due to commercial logging but to rapid population increases in the twentieth century when forests were cleared for cultivation and fuel. As such all opinions, ideas and investments on this blog might not work for you as they did for me. The energy required to produce oil from oil sands or tight oil (fracking) reserves is vastly more than the large conventional fields of Texas and Saudi Arabia.
